Its prime application is as the main sensor for data handling and weapon system control, and it has a very high performance in the presence of heavy clutter and electronic countermeasures. The equipment has been designed to cope with small high-speed anti-ship missiles with radar cross-sections down to 0.1 m2 and approach speeds of Mach 3+, which can be either sea skimmers or arriving from high angles of 70° or more.The SMART system operates in F-Band (the traditional of this frequency band name was S-Band, the designator is SMART-S therefore), where it offers an optimum balance between range, clutter rejection and antenna dimensions. It provides automatic detection, track initiation and track maintenance of both air and surface threats, with gapless coverage over a complete hemisphere from the sea surface upwards. It incorporates anti-clutter and electronic counter-countermeasures features such as multiple reception beams with ultra-low sidelobes in elevation and azimuth, a clutter analysis sensor, broadband transmission, pulse repetition frequency and radio frequency agility per burst and a jamming analysis sensor. SMART is designed to track 160 air targets and 40 surface targets simultaneously.The system comprises an antenna and three main below-decks units. The hydraulically stabilised antenna consists of a single-element wideband transmitting array, and a multi-element stripline receiving array. The ultra-low sidelobe phased array allows the formation of multiple receive beams in elevation. To ensure high sensitivity, preprocessing of the received signals takes place in the antenna unit itself. The output of the 16 antennas is fed to a digital beam forming network in which the 12 independent elevation beams are produced, after which Doppler <a href="http://www.radartutorial.eu/10.processing/sp15.en.html">Fast Fourier Transform</a> processing and automatic tracking is carried out. The transmitter is based on a high power, pulse-to-pulse coherent Traveling Wave Tube. Integral identification friend-or-foe can be provided.<img src="http://www.naval-technology.com/features/feature_images/feature1476/1-multi-beam-radar.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" />Video: <a href="http://www.youtube.com/watch?v=xyVoUr3tYyk">http://www.youtube.com/watch?v=xyVoUr3tYyk</a>Smart-S Mk2 – 3D medium to long range surveillance radarFuente: <a href="http://www.thalesgroup.com/Portfolio/Defence/Air_Systems_Product_-_Smart-S_Mk2/?pid=1568">http://www.thalesgroup.com/Portfolio/Defence/Air_Systems_Product_-_Smart-S_Mk2/?pid=1568</a>SMART-S Mk2, Thales’s latest 3D multibeam radar, operates in S-band and is optimised for medium-to-long-range surveillance and target designation in littoral environments.The latter consisting of a mix of sea, land, islands, coastal rains and thunderstorms and a multiple of radar targets including small surface targets, helicopters and anti-ship missiles. Furthermore, SMART-S Mk2 is designed to match the full performance of surface to air missiles (SAM), such as the Evolved Sea Sparrow Missile (ESSM).SMART-S Mk2 is extremely suitable as the main air and surface surveillance radar in a one radar concept for light frigates, corvettes and ships such as Landing Platform Docks (LPD). With its 2 main modes, 250-km range, special helicopter mode, surface fire channels, easy installation, high reliability and easy maintainability, SMART-S Mk2 is again a step forward in Thales’s radar development.Fuente: <a href="http://www.thalesgroup.com/assets/0/93/238/8bcd8450-178f-4670-93ea-1042456e865e.pdf?LangType=2057">http://www.thalesgroup.com/assets/0/93/238/8bcd8450-178f-4670-93ea-1042456e865e.pdf?LangType=2057</a>GeneralSMART-S Mk2, the newest Thales Naval 3D multibeam radar, is optimized for medium-to-long range air and surface surveillance and target designation. This stateof-the-art radar is an excellent performer in complex littoral environments with their mix of sea, land, rain, thunderstorms and targets such as multiple small surface ships, helicopters and anti-ship missiles. The detection range allows the full performance of new medium-range SAM-systems such as ESSM. Graceful degradation through the use of multiple solid state transmit modules and multiple receive channels ensures robust performance throughout the spectrum of military operations.Through the use of Doppler processing SMART-S Mk2 can detect even the stealthiest of targets in a cluttered environment by measuring radial speed directly. As a multibeam radar SMART-S Mk2 offers the long dwell time per target required for good radial speed measurements.SMART-S Mk2 is an optimal sensor for target indication to a fire control tracking system. By providing 3D tracks the radar supports correct classification and rapid acquisition. The elevation accuracy is high (even in case of multipath by using receive beams below the horizon) and suited to directly launch fire and forget missiles.SMART-S  Mk2 is well suited for detection of helicopters due to dedicated rotor hub detection capabilities. For guidance of helicopters and UAVs it can use very short pulses, providing a short minimum range.SMART-S Mk2 is designed for ease of maintenance and can support maintenance free missions. This is achieved by reducing single points of failures (graceful degradation), high MTBF per component, low MTTR and solidstate transmit modules.SMART-S Mk2 is easy to install on board. The antenna uses electronic stabilization. The solid state transmit modules are integrated in the antenna meaning no separate transmitter cabinet and waveguide are required. Foot print reduction is achieved through the use of powerful processing boards housed in a single processing cabinet. The total system weight is comparable to that of 3D G-band radars!Main characteristics• Excellent performance in the Littoral environment• Supports full performance of ESSM• Solid State Transmitter integrated in the Antenna• Low antenna sidelobes• Very small below deck footprint; just 2 small sized cabinets• Easily integrated with many CMS systems, both Thales and non-Thales• Short-range capabilities for surface detection, helicopter and UAV control• IFF antenna and optional integration with IFF system.Functional Aspects• 3D Air Surveillance with Fast Target alerts• Surface Surveillance• Surface Gun Fire Support• Jammer Surveillance• IFF Interrogation SupportPerformance Data• Maximum Instrumented range : 250 km• Maximum elevation coverage : 70 degrees• Minimum Range : 150 meters• Tracking 3D capacity (Air+Surface) : 500 targets• Surface Fire Control Windows : 3• Elevation accuracy : < 10 mrads• Bearing accuracy : < 5 mrads• Range accuracy : < 20 meters• Detection performance:Small missile : ~ 50 kmMPA : ~ 200 kmTechnical DataSystem:• Two operating modes: medium range up to 150 km at27 RPM and long range up to 250 km at 13.5 RPM• Fully automatic detection and tracking.• Dedicated ECCM techniques.Antenna:• Horizontal beamwidth : approx. 2 degrees• Illumination patterns : Wide beam and Narrow beam• Antenna rotation speed : 13.5/27 RPM• Stabilisation : electronic• Very low sidelobes• Integrated IFF antennaTransmitter:• Frequency band : E/F-band (excl.
